The novel features which are believed to be characteristic of the disclosure, both as to its organization and method of operation, together with further objects and advantages will be better understood from the following description when considered in connection with the accompanying figures. It is to be expressly understood, however, that each of the figures is provided for the purpose of illustration and description only and is not intended as a definition of the limits of the present disclosure.

Exemplary embodiments of the present disclosure relate to erasing the information stored in the mobile phone 101 SIM card memory, mobile phone memory including memory card sitting in the mobile phone when the owner of the mobile phone 101 loses his mobile phone 101. This would ensure security of the information sitting on the mobile phone 101 SIM card and mobile phone memory as well.

FIG. 1 is an exemplary block diagram of the system for erasing the information stored in the mobile phone 101 SIM card memory. The system includes but is not limiting to the Mobile Phone 101, Server 102 and communication device 103. Henceforth, mobile phone 101 SIM card memory and Mobile phone 101 memory are alternatively used throughout the description and both them refer to mobile phone SIM card memory. The server 102 henceforth alternatively referred as application server 102 and both of them refer to the server. In order to secure the information stored in the mobile phone 101 SIM card memory when the owner loses his mobile phone 101 or when fraudulent user steals the owner's mobile phone 101, the owner has to register with the server 102.

During registration process, the server 102 request for plurality of information from the owner of the mobile phone. The information required for registering includes but are not limiting to user name, mobile number, IMEI number, Mobile number, SIM card number, voice of the mobile phone owner and any other information required for the registration. After completing the registration process, the owner downloads the erase application onto the mobile phone 101 SIM card memory. The server 102 generates unique user name and password for the downloaded application and forwards it to the owner for his records. The generated user name and password are used by the mobile phone 101 owner to authenticate the mobile phone 101 and to activate the erase application whenever the owner wants to erase the SIM card memory contents. As an example, the owner may choose to erase the SIM card memory contents when his mobile phone 101 is lost.

In one embodiment, the mobile phone owner loses his mobile phone 101. In another embodiment the fraudulent user steals the mobile phone 101 from the owner. In both the cases the owner has to secure his information which is sitting in the mobile phone 101 SIM card memory. In order to do that the owner sends voice message to the mobile number associated with the lost mobile phone 101. The voice message includes the user name and password provided to him during the registration process. This voice message is routed to the application server 102. Here, the owner can send the voice message using any other communication device 103 which has the facility of creating voice message. The communication device 103 includes but is not limiting to mobile phone, telephone, and computers.

In one embodiment, the owner can dial a toll free number associated with the server 102 to provide required information to activate the erase application. The required information can be provided as voice message. However, any other communication mode can be used to supply the necessary information to the server 102. The information includes but are not limiting to user name, password and mobile number.

In one embodiment, when the voice message is transmitted to the server 102, it verifies the voice of the owner for authenticating the owner. Once the voice authentication is done, the server 102 records the voice message. However, the voice authentication feature could be made optional. In the next step, the server 102 verifies the user name and password associated with the erase application downloaded on the owner's mobile phone 101. If the verification is successful then it sends activation signal to activate the erase application. If the mobile phone 101 is not switched OFF, the erase application immediately activated upon receipt the activation signal from the server 102. When the mobile phone 101 is switched OFF or SIM card of the Mobile phone 101 is loaded into different mobile phone 101, the server 102 waits till the mobile phone 101 is switched ON. As soon as the mobile phone 101 having the SIM card is switched ON, the erase application in the mobile phone 101 checks for the incoming erase signal from the server 102. If the application finds any such signal it automatically get activated. Once the erase application is activated, it generates destroy signal to erase the information stored in the SIM card memory. The destroy signal includes but is not limiting to short circuit signal, reset signal and malware.

In an alternative embodiment, the erase application downloaded from the server 102 includes unique user name and password. When owner loses his mobile phone 101, he dials his number and provides the user name and password associated with the erase application. When server 102 receives the erase request from the owner, it sends the user name and password associated with the erase application. When the mobile phone 101 having lost SIM card is switched ON, the erase application sitting in the SIM card memory is automatically activated. Now, the erase application receives the user name and the password from the server 102 and compares it with the stored user name and the password. If the comparison is successful, the application erases the information stored in the SIM card memory.

In one embodiment, the erase application downloaded in the mobile phone 101 SIM card memory always checks for the erase request from the server 102 upon activation. If the erase application receives such request, then it will erase the information. If the application fails to receive the erase request then the application will be deactivated after predetermined time period. For example the time period may range from 1 second to 5 seconds.

FIG. 2 is a flowchart illustrating a method for remotely and automatically erasing the information stored on the mobile phone 101, in accordance with one embodiment. The instant method erases the mobile information, in particularly owner related information from the Mobile phone 101 SIM card memory without giving any clue to the mobile phone 101 holder. The method also performs the verification of the registered owner to know whether the request for erasing the information is placed by the registered owner or not. This would give first layer of security. Further, the method requests for the unique user name and password associated with erase application stored on the mobile phone 101 SIM card memory to activate the erase application. This would ensure additional layer of security. The step by step process used in erasing the information remotely and automatically is discussed herein below in detail.

At step 201, the owner who wants to access the facility of Erase Application has to register his mobile phone 101 with the service provider. The service provider requests the predetermined information for completing the registration process. Once, the required information is supplied by the owner, his mobile phone 101 is registered with the service provider. The service provider generates unique user name and password for the erase application to be downloaded on the registered mobile phone 101 and transmit them to the user through predetermined communication channel. This user name and password is required to download the application and to activate the application. The information required for registering includes but are not limiting to user name, mobile number, IMEI number, Mobile number, SIM card number, voice of the owner and any other information required for the registration.

At step 202, after registration process the owner has to download the erase application onto his mobile phone 101 SIM card memory. Alternatively, the server 102 of the service provider pushes the erase application onto the mobile phone 101 of the owner. In one embodiment the owner may require to provide the use name and password provided to the service provider to download the application. The user name and password includes but are not limiting to numeric numbers, alphanumeric, alphabets, and symbols.

At step 203, the owner loses his mobile without his knowledge or may be the mobile phone 101 has been stolen by fraudulent user. In that case the owner has to send his request to erase the information stored in the SIM card memory of the mobile phone 101. In order to do this the owner contacts the server 102 of service provider by sending voice message. Alternatively, the owner can dial the toll free number provided to him during the registration process and provides his mobile number, the user name and the password. The voice message includes but is not limiting to the mobile number, the user name and the password. Once, the server 102 receives the request through voice message or by dial-in, compares the mobile number, the user name and the password included in the voice message with the stored mobile number, the user name and the password. In addition to this, the server 102 may also performs voice authentication of the owner to verify the owner. If the credentials provided by the owner matches with the stored parameters then the server 102 takes necessary action.

At step 204, the server 102 sends activation signal to the application stored in the SIM card memory after verification of the owner details. Upon receipt of the activation signal, the erase application generates destroy signal to erase the information stored in the SIM card memory. In one embodiment, the server 102 may only perform voice authentication and sends the activation signal along with the user name and password required to activate the erase application. The erase application after receiving the activation signal compares the received user name and the password with the stored user name and the password within the erase application. If the received credential matches with the stored parameters then the erase application is activated at step 205. The activated application generates destroy signal to erase the information stored in the SIM card memory of the mobile phone 101 in which it is used. The destroy signal which is generated by the erase application includes but is not limiting to short circuit signal, reset signal and malware to erase the information.

In an alternative embodiment, the registered user downloads the erase application into the SIM card memory and a copy of the application sits into the mobile phone memory as well. This copy of the application is utilized to erase the information sitting in the mobile phone memory. The mobile phone memory includes memory card. The information sitting in the mobile phone memory and memory card are automatically erased whenever user loses his mobile phones. The application downloaded into the phone memory is activated regardless of whether a new SIM card inserted or not.

The phones these days and future development will have larger memory in the phone and less on SIM card and will be independent of the SIM card. If the SIM card is taken out by the fraudulent user without preset protected safeguard (similar to unsetting an alarm in a house before going out, contrast with an intruder coming in uninvited) either reset short circuit or malware will erase the information on the phone itself. If the rightful owner wants to take the SIM card out for whatever reason, after all it is phone, then he/she will have to deactivate the application by providing necessary login information including but are not limiting to user name and password. Alternatively, the user can deactivate the application through voice authentication, retina scan, and fingerprint detection. Once the application is deactivated, the owner can take out the card. The fraudulent user will not have access to the rightful owner's password and therefore will trigger the protective features of the application to erase the moment they pull the SIM card out.
